THEODORE R.,TIMBY, OF NYAGK, NEW YORK.

COOKING-VESSEL.

. SPECIFICATION forming part of Letters Patent No. 224,492,.datedFebruary 10, 1880.

Application filed July "1, 1879.

To all whom it may concern:

Be it known that I, THEODORE R. TIMBY, of Nyack, Rockland county, NewYork, have invented certain new and useful Improvements inCooking-Vessels, of which the following is a specification.

My invention applies to kettles, pots, boil ers, sauce-pans, or othervessels of stove or culinary ware constructed with a pendent jacketsurrounding the water-chamber, the lower edge of which rests upon thestovetop, and thus forms an annular heatingehamber around thewater-chamber, into which the heat is radiated and reflected against'thewater-chamber. My improvement liesin a shield or lining to the lowerportion of the said jacket, whereby the jacketisprotected against thedirect heat and its surface kept bright and cleanly, as hereinafterfully set forth.

In the drawing the figure presents a vertical central section of akettle constructed with my improved lined jacket.

As illustrated, it indicates the water-chamber of the kettle, which ispreferably of the form of an inverted truncated cone, its lower endbeing designed to be a loose lit for the stove-hole, so as to leave amarginal part of the said hole uncovered.

1) indicates the jacket, which is preferably of cylindrical form, anddepends from the upper part of the water-chamber, and terminates at ashort distance above the tapering base thereof, asshown, so that theWaterchamber isadapted to projeotinto the stovehole, While the jacketsurrounds the said hole and supports the kettle over the'same. It willnow be seen that the jacket-incloses an annular space aroundthewater-chamber, into which the heat from the stove-hole is radiated, andbeing reflected and confined by the said jacket upon the water-chamberon all sides thereof, the heating effect is thus greatly increased. V

Now, my improvement consists in providing the interior of the jacketwith the shield or lining c, which encircles the interior of the jacketat its lower part, and is preferably isolated slightly therefrom, exceptat its lower edge, Where it is turned over. and fixed to the lower edgeof the jacket, while from this point upward the shieldpreferably flaresoutward from the jacketflso as to form an insulating air-space betweenthe two, as illustrated.

The shield or lining preferably extends about three-quarters the heightof the jacket, as shown; but itsrelative height may be more or lesswithout objection, and as thus constructed it of course forms anintegral part of the jacket itself.

It will now be seen that the lower edge of the lining or shield restsupon the stove-top and protects the edge of the jacket or the .outerpart of the jacket from direct contact therewith. Furthermore, the heatfrom the stove-hole is radiated against the shield and thence thrownupon the water-chamber, thus elfectually preventing the directconduction or radiation of heat to the outer jacket, and hencepreventing the same becoming so highly heated as to waste much of thisheat by outward radiation, and at the same time preventing the outerjacket becoming quickly oxidized, thus enabling it to remainmuch longerin a bright condition, which is, of course, not only more pleasing inappearance, but is more favorable to the retention of heat and obviatesfrequent polishing. It will also be observed that the inward inclinationof the lining or inner jacket toward the water-chamber renders the samea much more efficient heating-reflector, as it reflects the heat at amore favorable angle downward toward the base of the water-chamber,which is, of course, the most favorable direction, as heat is largelywasted when applied to the top of a liquid. Hence by this improvement amuch better heating effect is obtained, while the outside of the vesselpreserves its bright appearance much longer, which are importantadvantages in aculinary article.

The improved vessel may be made of any suitable metal; but I ordinarilyprefer to form the water-chamber and jacket of copper and the shield ofbright tin; but the entire vessel may be made of one metal and be castor otherwise formed.

What I claim as my invention is- A cooking-vessel constructed with aheat-' confining jacket around its water-chamber,

with a shield or lining, 0, arranged at thelower part thereof, andadapted to protect the jacket from the direct heat, substantially asherein shown and described.

T. R. TIMBY.
